Previous studies have indicated the detrimental effect of missing breakfast on cognitive performance in school. The aim was to investigate the feasibility of utilizing functional magnetic resonance (fMRI) techniques with children and to examine changes in brain activity when undertaking cognitive tasks between a breakfast fasted and satiated state. Significant positive activations were found in Broadmann areas 6, 17 and 45 when comparing the satiated state to the fasted. The findings show that the impact of breakfast consumption can be observed through fMRI activated areas of the brain when completing cognitive tasks, compared to a fasted state in children.
